CST VerdictBased on our analysis of available product data, here is our conclusion:
Security teams building detection pipelines on a budget should start with Rapid7 Labs Repository; the curated Sigma and Yara rules are battle-tested against real malware samples, not theoretical attack chains. With 80 GitHub stars and free distribution, you get immediate IOC coverage without licensing overhead or vendor lock-in. Skip this if your team lacks the engineering bandwidth to integrate and customize rule sets, or if you need pre-built detection workflows that work out of the box; this is a foundation to build on, not a finished detection platform.
Threat hunters and SOC analysts running LOKI or THOR Lite scanners should use Signature-Base for its curated YARA rules and IOC database that requires zero tuning before deployment. With 2,885 GitHub stars and active community contributions, the rulesets catch real malware variants without the false positive noise that plagues generic public signature repos. Skip this if your team needs signature management across multiple scanner vendors; Signature-Base is purpose-built for the THOR ecosystem and won't reduce your operational overhead elsewhere.
